'My mother-in-law is 72 and has amazing skin - her secret is an obsession with one product'

However, while these changes are natural and unavoidable to some extent, it's possible to slow down and reduce the signs of ageing with the right tricks.

A woman in her 70s shared her secret to a beautiful complexion in her mature years, telling women that moisturiser is her best friend.

TikTok creator Dr Joyce Dermatologist introduced her mother-in-law, who is 72 and boasts a youthful complexion.

She said: "Everybody asks about her top skin care tips, given that she has amazing skin."

The skin-savvy septuagenarian said: "I had dry skin ever since I was a little girl, so I moisturise, moisturise, moisturise - that's the whole goal."

Moisturising is an essential skin care step that draws in moisture and retains it in the skin.

The 72-year-old shared that in addition to her face, she moisturises her hands every time she washes them.

Our hands often give the game away when it comes to our age, with tell-tale signs such as wrinkles or a crepey appearance, loose skin, prominent veins and age spots.

While moisturising the hands can't reverse all these skin concerns, it works by trapping water in our skin, which gives it a more youthful appearance.

Moisturiser is certainly hailed by skin care experts as an anti-ageing champion. It even helped one woman stay youthful in her 90s.

The skin experts at personal care brand Nivea advocated for the use of moisturiser to look younger.

They advised: "After both daily cleanses, be sure to apply a moisturising cream to keep the skin hydrated.

"This, combined with other active ingredients will help to maintain a smooth texture and reduce the appearance of fine lines and wrinkles."

Because moisturiser is so essential, it's essential to use it properly for maximum benefits - and you're probably doing it wrong.
